I do not believe the current status of DTrace is appropriate for promoting 1. DTrace is an experimental function or Semi-finished products. The kernel dtrace support is ok, but the userland support is far from completion(at least the pid provider has many bugs) 2 the FreeBSD implementation is different from Solaris/Mac OS X. The DTraceToolkit, which has many amazing feature, can not 100% works on FreeBSD, and there is no doc to identify the difference. 3 There is a missing feature list about DTrace, but no schedule list about when to fix it. 2011/8/30 Sergey Kandaurov <pluknet@gmail.com> > On 30 August 2011 13:13, Hartmann, O. <ohartman@zedat.fu-berlin.de> wrote: > > On 08/30/11 09:29, Hans Petter Selasky wrote: > >> > >> On Monday 29 August 2011 21:58:29 Volodymyr Kostyrko wrote: > >>> > >>> 27.08.2011 22:13, Hartmann, O. wrote: > >>>> > >>>> This website should be brushed up or taken offline! > >>>> It seems full of vintage stuff from glory days. > >>>> > >>>> http://www.freebsd.org/marketing/os-comparison.html > >>> > >>> I think this one would better look like list of major features with os > >>> comparison, like: > >>> > >>> = Networking = > >>> * IPv6: major support, best stack around. > >>> * SCTP: full kernel implementation, still no userland support (i.e. > >>> ssh doesn't work over sctp by default yet). > >>> > >>> = Data storage = > >>> * ZFS: full support, datasets, compression, dedup, other stuff.
